Answer:
Step-by-step explanation:
Person who wears a watch + ring
Lets say the fraction of people wearing the rings is 1/X
Lets say the fraction of people wearing a watch is 2/y
The formula is multiplication for both (Key words: and)
The formula is add for one or the either (key words: or)
The question says that person wears a watch given that they wear a ring
It mean that they wear a watch + a ring.
THat mean multiplication!
Lets use the example: 1/x · 2/y = 2/xy
This makes 2/xy your answer for the example.
Now lets do another example:
Lets say the fraction of people wearing the rings is 1/3
Lets say the fraction of people wearing a watch is 2/3
Multiplication!!!!
1/3 x 2/3 = 2/9
This makes 2/9 your answer to this example!!!!
C. 1.2
D. 1.25
A 3x - 1 = 3x + 1
® 2x - 1 = 1 - 2x
© 3x - 2 =2x-3
D 3(x - 1) = 3x - 3
Answer:
D
Step-by-step explanation:
In order to have infinitely many solutions, the lines must be the same.
If we solve D by using the distributive property, we end up withe 3x-3=3x-3.
3x-3 and 3x-3 are the same lines and intersect infinitely many times, therefore the correct answer is D.
